             Summary: Incorrect Content-Length for ChangeSet in $batch
                 Key: OLINGO-256
                 URL: https://issues.apache.org/jira/browse/OLINGO-256
             Project: Olingo
          Issue Type: Bug
          Components: odata2-core
    Affects Versions: V2 1.2.0
            Reporter: Michael Bolz


When using the {{EntityProvider.writeBatchRequest(batchParts, boundar);}} method to create a *$batch* request which contains {{BatchChangeSetParts}} the calculated *Content-Length* of the changeset body part is not correct (regarding to "http://www.w3.org/Protocols/rfc1341/7_2_Multipart.html").

This results in exception when using strict multipart parsers (like sample service at "http://services.odata.org/V2/OData/OData.svc/$batch") which response with:

{code}
--batchresponse_bbd3caec-0224-49c9-8bf0-75a1365853fb
Content-Type: multipart/mixed; boundary=changesetresponse_054f8f41-e12f-46bb-922b-3dc234e2f27b

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
  <code></code>
  <message xml:lang="en-US">Error processing batch request. The request is not a valid batch request.</message>
</error>
--batchresponse_bbd3caec-0224-49c9-8bf0-75a1365853fb--
{code}
